Distinguishing Between Bed Bug Bites and Mosquito Bites
Bed bugs and mosquitoes are two of the most notorious biting pests that can make your life miserable. But while their itchy bites may appear similar at first glance, there are important differences to learn in order to identify which pest is biting you.
Examining the bite patterns, appearance, and symptoms can help decipher whether you have been feasted on by bed bugs or mosquitoes. Understanding the distinctions will ensure you take the proper steps to get relief and eliminate the infestation.
Appearance of Bites
Lets start by comparing how bed bug bites and mosquito bites typically look on the skin:
Bed Bug Bites
- Small, red, raised bumps or welts
- Often appear in a clustered or linear pattern
- May have a white or swollen center
- Some bites can develop into larger welts
Mosquito Bites
- Small, round red bumps
- Usually appear isolated rather than clustered
- Often have a central raised white bump
- Surrounded by pink or red flare
Bite Patterns and Locations
Another key difference is where on the body the bites tend to appear:
Bed Bug Bites
- Usually concentrated on exposed skin such as arms, shoulders, neck, face, ankles
- Often appear in lines or zig-zag patterns
- Bites can occur anywhere on the body
Mosquito Bites
- Most often on feet, ankles, and legs
- Can also be found on forearms, wrists, and other exposed areas
- Bites are typically more scattered and random
Number of Bites
The number of bites present can also indicate what pest you are dealing with:
Bed Bug Bites
- Feed mostly at night, so waking up with bites is common
- Produce clusters of 3-4 bites, up to 20 bites in severe infestations
- New bites appear nightly as bugs return to feed
Mosquito Bites
- Cause fewer bites, typically just 1-3 bites at a time
- Dont bite in rapid succession like bed bugs
- New bites taper off once removed from the source
Size of Bites & Swelling
The size of the raised bumps and degree of swelling indicates the type of biter:
Bed Bug Bites
- Individual bites are small, but can swell and form larger welts
- Repeated bites lead to significant inflammation and swelling
- Bites can swell dramatically, to the size of a quarter or larger
Mosquito Bites
- Bumps remain relatively small, about 1/8 to 14 inch diameter
- Mild to moderate swelling, but welts are smaller than bed bug bites
- Very little swelling or inflammation overall
Symptoms and Sensations
Bites from bed bugs and mosquitos also differ in how they look and feel:
Bed Bug Bites
- Extremely itchy, severe itching is common
- Bites may burn or sting before intense itching sets in
- Itching can last for several days or longer
- May cause discomfort, pain, or tenderness
Mosquito Bites
- Itchy, but less severe than bed bug bites
- Stinging or burning sensation right after being bitten
- Itching subsides after a day or two
- Usually dont hurt or feel sore unless excessively scratched
Potential Reactions
Allergic responses and other secondary symptoms also differ between the two pests:
Bed Bug Bites
- No allergic potential, but trauma from repeated feeding can trigger hive-like rashes
- Excessive scratching can lead to infection
- Highly anxious, sleep loss common when infestation is severe
Mosquito Bites
- Saliva may cause mild to severe allergic reaction in some people
- Can develop into swollen wheals, blister-like bumps, etc.
- Low risk of infection or significant skin trauma
How to Avoid Bites
Preventing exposure is the best tactic against bed bug and mosquito bites. Recommendations include:
For Bed Bugs:
- Carefully inspect secondhand furniture before bringing home
- Isolate and heat treat luggage after traveling
- Reduce clutter and seal cracks/crevices in bedrooms
- Encase mattresses and box springs in covers
- Treat infestations early with professional insecticides
For Mosquitoes:
- Limit outdoor time at dawn/dusk when mosquitoes feed
- Wear long sleeves and pants when outside
- Use EPA registered insect repellents
- Install screens on windows and doors
- Remove standing water sources like flowerpots, gutters, etc.
Treating Bites for Relief
Although bed bug and mosquito bites look similar, its important to know what bug bit you so that you can both treat the bites for relief, and take steps to eliminate the infestation. Heres how to manage bites from each pest:
Bed Bug Bites
- Use topical corticosteroid cream to reduce itching and inflammation
- Apply a paste of baking soda and water to relieve itching
- Take an oral antihistamine containing diphenhydramine
- Apply cool compresses to decrease swelling
- Resist scratching to avoid infection; trim nails short
Mosquito Bites
- Use OTC hydrocortisone cream, calamine lotion, or baking soda paste
- Apply ice pack or cool compress to bite site
- Take an oral antihistamine for swelling and itching
- Apply antibiotic ointment if bite is scratched open to prevent infection
- Avoid scratching; applying nail polish can deter scratching
Preventing Infestations
Getting rid of bed bugs or mosquitoes requires different control tactics:
For Bed Bugs:
- Inspect and seal hiding spots in walls, furniture, bedding
- Use EPA approved insecticidal dusts or sprays in infested rooms
- Wash and heat treat clothes, bedding on hottest settings
- Isolate heavily infested furniture in sauna-like rooms to kill bugs
- Consider professional extermination if self-treatment fails
For Mosquitoes:
- Drain standing water sources where mosquitoes breed
- Use BTI larvicides/dunks in water gardens, ponds
- Keep grass trimmed and landscape tidy to reduce resting spots
- Use outdoor yellow bug lights to deter mosquito entry
- Employ mosquito misting systems and backyard sprays
When to See a Doctor
In most cases, bed bug and mosquito bites can be managed at home. See a doctor if:
- Bites become severely swollen, weeping, or infected
- You experience signs of anaphylaxis after being bitten such as trouble breathing
- Itching, swelling, and discomfort are not relieved by over-the-counter treatments
- You develop a high fever, headache, body aches that could indicate West Nile virus or malaria from mosquitoes
Be sure to get treatment early, as infections related to scratching can progress quickly. Seeking medical care is especially important for babies, children, pregnant women, and the elderly who are most vulnerable to complications.
The Takeaway
Learning to distinguish a bed bug bite vs mosquito bite can help guide management. Compare the pattern, appearance, and sensations of any mysterious bites against the common characteristics of these pests. While all bites may look somewhat similar at first, the details can shed light on what is feasting on you at night.
Quickly eliminating the infestation and resisting the urge to excessively scratch are key to getting relief from the uncomfortable bites. With proper treatment and prevention, you can enjoy pest-free sleep again.
